Sir Julian Lewis: I warmly endorse almost everything the Secretary of State has said today, and I genuinely congratulate him on his appointment. In my first speech in this House almost 30 years ago, I promised to support Labour Governments as long as they supported the nuclear deterrent, the conventional armed forces and NATO. I would like to think that I have kept that promise.

The one area where I have to dissent, however, is the section where he comes on to the proportion of GDP spent on defence. As I have said to some of the right hon. Gentleman’s predecessors, it is no good banging on about something being the largest increase since the end of the cold war. We are now in a situation that is worse than that at the height of the cold war, so the comparison we have to make is between what we are spending now and what we spent during the cold war, which was, in modern calculating methods, between 4.5% and 5.1% on defence. So let us not talk about increases to 2.7%. We really must remember that even when the Berlin wall came down, we were spending over 4% of GDP on defence at that stage. Those are the sorts of efforts that we have to make, because if Putin fails in Ukraine, the threat to this country will recede for a generation.

[The Secretary of State for Defence (Wes Streeting): I give the right hon. Gentleman an undertaking on those three things to make it as easy as possible for him to support this Government: supporting the nuclear deterrent, building capacity in our armed forces and supporting NATO are things I believe in very strongly. In the spirit on these exchanges, I will take at face value the point he makes about the comparison with the cold war and resist the temptation to discuss the starting point we were faced with on defence spending and the condition of our armed forces when this Government arrived.

The right hon. Gentleman is right to draw historical comparisons and provoke all of us to think more widely about the context we are operating in domestically, across Europe and internationally. I have not heard a suggestion from the official Opposition that the Government should be making a 4% or 5% commitment, nor any proposals to that effect, but let this discussion help the public understand why, at a time of constrained resources for households, businesses and Government, we are making an active political choice to invest more in our defence. I respectfully say, as someone who has been responsible for hospitals and the NHS, that schools, hospitals and homes are important things, but they are valueless if reduced to rubble. That is the experience of the Ukrainians; that is the kind of threat that we are operating under; and that is why we must commit, and continue to commit, to increasing defence spending.]
